The process of files being damaged resulting from some hardware or software failure is called data corruption and this is one of the main problems that Internet hosting companies face since the larger a hard disk is and the more info is stored on it, the much more likely it is for data to get corrupted. There're various fail-safes, but often the data becomes damaged silently, so neither the particular file system, nor the administrators detect a thing. As a result, a damaged file will be treated as a good one and if the HDD is a part of a RAID, that file will be copied on all other drives. In theory, this is for redundancy, but in practice the damage will be worse. Once a file gets corrupted, it will be partly or entirely unreadable, therefore a text file will not be readable, an image file will show a random combination of colors if it opens at all and an archive will be impossible to unpack, so you risk sacrificing your site content. Although the most commonly used server file systems include various checks, they quite often fail to discover some problem early enough or require a long period of time to be able to check all the files and the web server will not be functional for the time being.
No Data Corruption & Data Integrity in Website Hosting
The integrity of the data which you upload to your new website hosting account will be ensured by the ZFS file system that we employ on our cloud platform. The vast majority of web hosting service providers, including our firm, use multiple hard disks to store content and because the drives work in a RAID, identical data is synchronized between the drives at all times. When a file on a drive is corrupted for whatever reason, yet, it is likely that it will be duplicated on the other drives as other file systems do not have special checks for that. In contrast to them, ZFS works with a digital fingerprint, or a checksum, for every file. In case a file gets damaged, its checksum won't match what ZFS has as a record for it, which means that the bad copy shall be replaced with a good one from another disk drive. Since this happens right away, there is no possibility for any of your files to ever be damaged.
